Abstract

People with HIV (PWH) are living longer and experiencing a greater burden of morbidity from non-AIDS-defining conditions. Chronically treated HIV disease is associated with ongoing systemic inflammation that contributes to the development of chronic conditions (eg, cardiovascular disease) and geriatric syndromes (eg, frailty). Apart from HIV disease, a progressive increase in systemic inflammation is a characteristic feature of biologic aging, a process described as "inflammaging." Inflamm-aging is driven by persistent antigen stimulation and stress, leading to an immune profile characterized by elevated levels of blood inflammatory markers and cellular activation and senescence. Chronic HIV disease is hypothesized to accentuate the immune profile of inflamm-aging, in part through viral persistence in lymphatic tissues, permanent injury impairing immune recovery, the presence of copathogens, gut dysbiosis and microbial translocation, and chromosomal and genetic alterations associated with immune activation. Few strategies exist for safe and effective modulation of systemic inflammation among older PWH. The strongest current evidence supports aggressive management of modifiable risk factors such as lipids, blood pressure, and levels of physical activity. Future inflamm-aging research should be directed toward advancing the implementation of proven approaches, such as physical activity, as well as studying novel mechanisms of, and treatments for, inflamm-aging among PWH.
